Type: | Domain | Name: | Cobalamin (vitamin B12) biosynthesis CbiX |
Description: | This entry represents sirohydrochlorin cobaltochelatase (also known as CbiX), which catalyses the insertion of Co2+ into sirohydrochlorin as part of the anaerobic pathway to cobalamin biosynthesis. The structure of CbiX from Archaeoglobus fulgidus consists of a central mixed beta-sheet flanked by four alpha-helices, although it is about half the size of other Class II tetrapyrrole chelatases []. The CbiX proteins found in archaea appear to be shorter than those found in eubacteria []. | Short Name: | Cbl_biosynth_CbiX |
